Patented May 27, 1930 UNITED STATES GUNTHEB HARTMANN, OFV'IETZ, GERMANY DRYING FRAME WITH TRANSVERSE LATHS Application filed September 30, 1927, Serial No. 223,184, and in Germany October 6, 1926.

This invention relates to a drying frame for drying bricks and the like. The novelty of this drying frame consists in that it is fitted on both ends, on the upper side as well as on the lower side of the frame, with transverse laths of suitable height. To the transverse laths is given preferably such a height that the material to be dried when placed on the frame stands a short distance from the next higher frame. The transverse laths serve, on the other hand, to make it possible to pile one frame over the other so that after they have been filled with bricks and the frames piled, transportable drying stands are formed, 16 which can be conveyed as a whole on suitable trucks. The upper and lower transverse laths are connected with the longitudinal boards by screw bolts and they have shallow countersinks for the heads and deeper countersinks for the nuts in order that the several frames may lie the one on the other by means of the transverse bars either without projecting screw elements or by using the nuts as tenons when the bolt heads engage with the deep countersinks and the nuts engage with the shallow countersinks so that the piled up drying frames filled with bricks cannot shift in lateral direction during the conveying.

The height of the transverse laths may evidently be selected at will and this depends on the height of the bricks. The clear space between two superposed frames must be slightly greater than the height of the bricks, in order that these bricks are accommodated with clearance and that the air can pass freely at every point. The length of the frames may also be selected at will and it depends on the number of bricks to be placed on the frame and the spaces between them. The fresh bricks are placed on the frames at the brick yard and the completely filled frames are conveyed to the drying place for instance by a truck of known type.

In the accompanying drawing the drying frame and the stand formed of these frames are illustrated in several forms of construc tion by way of example.

The drying frame A consists (as shown in Figs. 1 to 9) of a plate composed of longitudinal laths a spaced the one from the other 63 or not. The laths a are connected on the upper side and on the lower side by transverse laths Z2 standing vertical and of suitable height corresponding to the dimensions of the articles to be dried. The transverse 7o laths b may be fixed at the ends of the horizontal or longitudinal laths a or, as shown in the drawings, at a short distance from said ends, so that the projecting portions of the horizontal laths a serve as handles. For forming a drying stand the several frames A, on which bricks cl or other articles to be dried have been placed, are superposedas shown in Fig. 3. To protect the material to be dried against rain the stand may be covered in a so convenient manner.

Figs. 4 and 5 show drying frames A, in which the longitudinal laths a have between the vertical transverse laths b transverse boards (Z fixed by nails. These frames are used when moulded articles of soft material are to be dried.

Figs. 6 and 7 show in side elevation and top plan view a drying frame composed of four horizontal boards a placed close together and designed for drying moulded articles of soft material, so that the entire bottom surface of the moulded articles rests upon the boards a. Fig. 8 shows how a shed is formed from the frames shown in Figs. 6 and 7 the moulded bricks (i being placed on these boards a.

Fig. 9 shows in top plan view the frame shown in Figs. 6 and 7 with the bricks d placed on the same. In Figs. 10, 11 and 12 the connection of the upper and lower vertical transverse laths b is shown in different forms of construction. The connecting bolts 6 traverse the transverse laths b and the longitudinal laths a. The heads f of the connecting bolts are located each in a shallow countersink, the nuts 9 being located each in a deep countersink in the transverse laths b so that the nut does not project from the corresponding end of the lath, as shown in Fig. 10.

The countersinks in the transverse laths are lined with metal sleeves it having a bottom plate or not.

In the form of construction shown in Fig. 11 the connecting bolts 6 are arranged so that the fiat head f rests in the deep countersink, the nut g resting in the shallow countersink so that it slightly projects over the top edge of the transverse lath b and engages with the deep countersink of the next higher frame whereby lateral displacement of the frames A is prevented.

1. A drying frame comprising horizontal J longitudinal laths and transverse laths on both ends and both faces of the aforesaid laths, the exposed upper and lower faces of the transverse laths having counter sinks, a metal sleeve having its bottom closed and inserted in each countersink and bolts passing through the sleeves and countersinks of each pair of transverse laths, one end of each bolt projecting from a. countersink and sleeve.

2. A drying frame consisting of horizontal,

longitudinal laths, a pair of vertical transverse laths at each end of the longitudinal laths and between which the longitudinal laths are placed, the exposed edges of the transverse laths having countersinks, metal sleeves having removable bottom plates mounted in the countersinks and bolts passing through the sleeves, bottom plates, transverse and longitudinal laths, the threaded end and nut of each bolt projecting from its countersink for engaging in a corresponding countersink of a superposed frame.

3. A drying frame consisting of horizontal longitudinal laths, and of transverse laths on both sides in which in the transverse laths a shallow countersink is provided in the upper end and a deep countersink in the lower end, bolts connecting the laths together said shallow countersink being designed for the nut and said deep countersink for the head of a connecting bolt, said nut projecting over the top surface of said transverse laths for engagement with a countersink of a vertically adjacent lath of another drying frame.

4:. A drying frame comprising longitudinal laths and at each end a transverse lath above and one below the longitudinal laths and in vertical alinement, countersinks in the upper face of the upper transverse lath and in the lower face of the lower transverse lath and identical bolts passing through the trans-
